摘要:
Two glass plates on a bending mold are heated in a heating/bending furnace so that they are subjected to provisionally deep-bending operations by their own deadweight, and the provisionally shaped deep-bent portion is pressed by an auxiliary pressing member to thereby form a laminated glass for, for instance, an automobile.

摘要:
Glass plates for a laminated glass are bent and strengthened by provisionally shaping by heating two overlapping glass plates placed on a deadweight bending mold having a shaping surface by elevating the temperature to a temperature capable of bending glass and by locally heating side portions of the two overlapping glass plates to be deeply bent at a higher temperature in a heating/pressing stage so that the two overlapping glass plates are provisionally shaped by their own deadweight into a shape substantially corresponding to the shape of the shaping surface of the bending mold, pressing a portion of the two overlapping glass plates to be deeply bent from the top by a pressing member after the provisional shaping step in a heating/pressing stage, separating the two overlapping glass plates from the bending mold by pushing up the portion of the glass plates other than the deeply bent peripheral portion of the two overlapping glass plates thereby cooling the peripheral portion of the glass plates in a peripheral portion strengthening stage, and cooling the overlapping glass plates to atmospheric temperature.

An object of this invention is to provide a charged particle beam apparatus that can easily evaluate the stability of a position that is irradiated with a charged particle beam.To achieve the above object, this invention includes a detector that scans a charged particle beam and detects secondary particles that originate from a substrate, and an image processer that displays an image of the substrate on a display based on the secondary particles that are detected by the detector. The image processer is configured to display on the display any two or more members of the group consisting of a scanning image produced by the charged particle beam of the substrate, a wave in time domain showing fluctuations of the irradiation position of the charged particle beam on the substrate, and a power spectrum of the wave in time domain.
